3 Claims.

This invention appertains to new and useful improvements in means for removing ice from pavements in a quickand efiicient manner.

The principal object of the present invention is to provide a cutter attachment for trucks and other vehicles which can be moved along an ice covered street or pavement for the purpose of efficiently removing the ice without damaging the pavement.

Other important objects and advantages of i the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a fragmentary side elevational view showing the cutter applied to a truck,

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 generally refers to a conventional truck such as is generally employed in pushing snow plows and the like. This truck is provided with the usual rear axle housing 6 with which is engaged the U-clamp l on the tail portions 8-8 of the rearwardly disposed arms 9-9, which are provided with crossed braces I0. Adjacent the forward ends of these arms 9-4] is the bridge piece ll raised at its intermediate portion, Hinge members l2-I2 connect the forward to the elongated plate i3. has its diverged leg porto the plate l3 while its trunk portion underlies the bridge member I I and is apertured to receive the reduced portion [6 at the lower end of the screw 47, which screw is threadedly disposed through the nut ill on the bridge member II and is provided with a polygonal-shaped head l9 with which a wrench or other tool can be engaged. The lower end of the reduced portion l6, that is, the portion below the Y-shaped member I 4 is provided with the head perspective view of one of I the tions secured asat I5 l 20 to prevent displacement of the Y-shaped memher from the screw 11.

Obviously, adjustment of the screw ll will result in changing the inclination of the plate l3 and the cutter bar M. This cutter bar 2i includes the elongated member 22, the edge portion 23 of which is beveled to engage the beveled edge portion of the backing strip 26 which is-secured to the bottom side of the plate It.

Extending forwardly from the strip 22 are the notched teeth 25. These teeth are notched to pro- 5 vide spur-like ends 26 which cut into the ice and rip the same loose from the pavement.

Extending forwardly from the plate iii and at the ends thereof are the arms 2'l-2l each of which has secured at its outer end by a clamp 28, 0 a lead cutter tool 29 which serves to cut a path in the ice within which the cutter bar 2! is to operate.

The transversely slidable cutter bar 2! is provided with slots 38 therein having beveled edge portions for receiving the edge beveled blocks 3! which have threaded recesses 32 therein for receiving the screws 33. These screws are disposed through openings in the plate It. Thus the cutter bar 2l is slidably mounted on the plate i3.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing fromthe spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed asnew is:--

1. An ice remover comprising a vehicle attaching structure, a transversely disposed plate on the attaching structure, and a cutter bar slidably disposed on the plate, and adjusting means between the plate and the vehicle attaching structure, said means consisting of a hinged connection between the vehicle attaching structure and the plate, a 5 member extending from the plate to interlap the vehicle attaching structure, and a screw disposed through the vehicle attaching structure and con-- 7 nected to the said member.

2. An ice remover comprising a vehicle at- 40 tached structure, an ice engaging blade hingedly connected to the vehicle attaching structure, said blade being provided with an arm projecting therefrom, and under the vehicleattaching structure, and adjusting means the vehicle attaching structure.

3. An ice remover comprising a vehicle attached structure, an ice engaging blade hingedly connected to the vehicle attaching structure, said blade being provided with an arm projecting therefrom, and under the vehicle attaching structure, and adjusting means between the arm and the vehicle attaching structure, said adjusting means consisting of a screw feedably disposed through the vehicle attaching structure and having one end swivelly connected to the said arm.
